AERATING AND WATER PUMP.

SPECIFICATION forming part of Letters Patent No. 438,061, dated October7, 1890.

Application filed April 3, 1890. Serial No. 346,377. (No model.)

T0 at whom it may concern.-

Be it known that I, ROBERT I-I. DAOUS, of Dardanelle, in the county ofYell and State of Arkansas, have invented a new and Im proved Aeratingand Vat-er Pump, of which the following is a full, clear, and exactdescription.

My invention is an improvement in that class of pumps which are adaptedboth for raising water and simultaneously introducing air into the tankor well from which'it is drawn. Heretofore the pumps devised for thispurpose have usually been too complicated, bulky, and expensive to adaptthem to the economical and other requirements of ordinary use, and Ihave therefore devised an aerating attachment for an ordinary forcepumpwhose simplicity of construction enables it to be easily applied atsmall cost, and whose efliciency equals that of the most expensiveapparatus for a like purpose.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the complete device viewed in directionof an arrow in Fig. 3. Fig. 2 is a side elevation viewed from the samepoint as Fig. 1, the main portion being broken into section showing theinterior. Fig. 3 is a plan in sectiontaken on the line 3 3 in Fig. 1.Fig. 4 is a plan in section taken on the line 4 4 in Fig. 1, and Fig. 5is a sectional side elevation taken on the line 5 5 in Fig. 1 and viewedin direction of an arrow in said figure.

I will first briefly describe the parts of the pump to which my aeratingattachment is applied.

Two cylinders A and B, having, respectively, pistons m and 0 and acommon pistonrod u, are arranged in vertical alignment and screwed intoan intermediate chambered union-coupling C. An ordinary water-dischargepipe f connects with one of the chambers e of this coupling and anair-tube g with the chamber 6 on the opposite side. Avalve a, adapted toopen upward, is arranged at the head I) and coupling 0, as shown best inFigs. 1 and 4.

My aerating attachment is composed of the following parts, constructedand arranged as stated: A chambered cap=piece h, having a stufling-box pfor the piston-rod n, is applied to and forms the head of theair-cylinder B,

and is secured in place by rods 2', that pass through ears 2" of the capit and coupling 0, as shown in Figs. 1 and 3. This cap-piece h hasscrew-threaded nipples h on opposite sides to provide for convenientattachment of the valved tubes is and 70. To one lo of these tubes isattached an air-conducting pipe S, which extends downward and inpractice enters the .water alongside the lift-pipe b, as best shown inFig. 5. An upwardlyextending air-inlet pipe 0" is attached to the othervalve-tube 7c.

It will be noted, Fig. 5, that the valves in tubes is is open in thesame direction and operate as check-valves to allow passage of air frompipe 1" into the cylinder B and from the latter into pipe S, but preventits return.

In practical operation, when the rod u, with its attached pistons m and0, is reciprocated, water is drawn into cylinderA on the upstroke, andair is simultaneously expelled from cylinder B into pipe S, and by itconducted down into the water. On the return or down stroke air entersthe cylinder B through pipe 1" to supply the vacuum behind thedescending piston 0, and the piston in of cylinder A. allows the watertherein (which entered on the upstroke) to pass above it. Then on thenext upstroke the water is expelled through pipe f, (being cushioned bythe air between the piston and in the standing tube 9,) and air is againforced through pipe S into the body of water in the well or tank. Thisattachment-composed, essentially, of the parts h S a" k k, as abovedescribedis simple and inexpensive, yet efficient, and may be appliedwith but slight changes, requiring nothing but ordinary mechanical skilland judgment, to the upper cylinders of pumps of various common kinds.

What I claim is- 1. The improved aerating attachment for pumps, the sameconsisting of the cap-piece h for a pump-cylinder, valved tubes k and k,

10 specified, of the aerating attachment, consisting of the cap-piece h,applied to cylinder B, the lateral valved tubes 70 lo, theair-conducting tube S, arranged vertically pendent alongside saidcylinders, and the air-inlet tube 1*, all as shown and described, andadapted x 5 to operate as specified.
